I have 5 buff orpington hens with a rooster. I want to see if they could hatch their own eggs. I am doing a bunch in an incubator, but thought it would be neat to let the girls try. Any tips for what I need to do? How long should I leave eggs in the boxes waiting for someone to sit on them? If they don't get broody should I toss the eggs or are they still edible. I haven't collected eggs in about 3 days in hopes that all I need to do is leave them alone and the hens will do the rest.
